Complex Routing For Get Request From Html Form In Flask

I'm trying to create complex routing for a get request that looks like this: @app.route('/get-details?id=&code=', methods=['GET']) @login_required

Solution 1:

Don't put query args in the route definition. Instead, get them from request.args. args.get takes an optional type argument, so you can still validate the type of the value.

@app.route('/get_details')defget_details():
    id = request.args.get('id', type=int)
    code = request.args.get('code', type=int)
    ...

For the solution to your specific error, read the error message. You have a route with two url groups, but you don't supply values for them to url_for. Since you only know the args after the form is filled out on the client, this becomes a good argument for why you don't put query args in the route.

url_for('get_details', id=2, code=108)
